Specification of Letters Patent.

Patented July 28', 1914.

Application filed Kay 16, 1914. Serial No. stanza.

To all whom/it may concern v Be it known that I, LADISLAS Loni, asubject of the King of Hungary, residing at C- lumbus, in the county ofFranklin and State of Ohio, have invented certain new and usefulImprovements in Parachutes, of which the following is a specification.

An object of the invention is to provide a parachute that is socontrolled from a carriage as to determine the velocity of descent ofthe same.

A further object of the invention is to provide a parachute with ribs,stretchers, and a runner, with ropes connected to the edge of theparachute cover and terminating in a single cable to be wound upona'windlass disposed within the parachute carriage, so that the cover maybe opened or closed the desired distance to control the velocity ofdescent of the parachute.

\Vithfthe above and other objects in view that will appear as the natureof the invention is better understood, the same consists in thenovelconstruction, combination and arrangement of parts to be hereinaftermore fully described and then claimed.v

In the accompanying drawing in which is shown apreferred embodiment ofmyinvention and to which reference is had herein by like charactersdesignating corresponding parts throughout the several views Figure 1 isa vertical sectional view of the parachute distended. Fig. 2 is avertical sectional view of a portion of the, device with the coverremoved. Fig. 3 is a' horizontal sectional view of the same taken online III-III of Fig. 1, and, Fig. 4'is a detail sectionalview of aportion of the carriage frame for reducing friction on the ropes.

Referring 'morein detail to the accompanying drawing, the referencenumeral designates the tubular rod which consti tutes the central shaftof the parachute and is exteriorly threaded at its upper end for thereception-of the head cap 11. The head cap 111s suitably recessed in itssides for the reception of the upper ends of the ribs .12, the ribs 12being'pivoted thereto as at 13 while the lower ends of the said-ribs areprovided with eyes 14. Mounted on the tubular rod 10 is a runner 15 andextending between the runner 15 and the ribs 12 are the stretcher arms16. A cover of canvas or other suitable material as 17 is rovided and isconnected to the ribs 12 and ead cap 11 in the usual manner and is of asize in distended position to prevent the runner 15 descending to apointwhich would place the stretcher arms 16 in horizontalposition.

A carriage is suspended from the tubular member 10 and consists of theside arms 18 inclined upwardly and inwardly and fixed to the lower endof the tubular member 10 as at 19, while the lower ends thereof'supportthe bottom 20 of the carriage, an

side rails 21 extend about the lower ends of the side arms '18. mountedupon the bottom 20 of the carriage and has wound thereon a cable 23, thecable 23 being the continuation of a plurality of ropes 24' extendingbetween the eyes 14 of the ribs 12 andthe point 25 of the said cable.Means are provided to reduce the friction and wear on the ropes 24 andconsist of the rollers 26 suitably supported in the frame 27 connectedto the side arms 18, the ropes'24' passing over the rollers to the point25, the said rollers 26 being mounted on the shafts 28.

In collapsed form the parachute resem-. blesthe ordinary type. distendedas shown in Fig. 1, the velocity of the descent is controlled -by aperson within" the carriage. By operating the Windlass 22 to windthereon the cable 23, the ropes 24- are moved inwardly the desireddistance. to reduce in size the parachute covering 17 thereby reducingthe resisting surface of the cover and permitting the parachute todescend more rapidly. In order to provide for a gradual descent, thecable 23 1S 11I1 W0l1I1d from the Windlass 22 which will permit the ribs12 to be distended, thereby increasing the resistance surface of thecover17. By operating'thewindlass, the parachute may be entirely closedand in view of the particular size of the covering 17 as beforementioned, the runner 15 is prevented from descending to a point whereit would be impossible to collapse the same.

While I have herein'shown and described the preferred embodiment of myinvention, I do not wish to confine myself to the exact details ofconstruction as shown, as various forms; modifications and arrangementof the parts may be had without departing from the spirit and scope ofthe invention as claimed.

What I claim as new is V 1. In a parachute, a central tubular rod, ribspivoted at their upper ends to said rod,

When the same is.

A Windlass 22 is a runner mounted on the rod, stretchers extendingbetween the runner and the ribs, a canvas covering for said ribs, acarriage suspended from the lower end of the. rod, ropes connected tothe lower ends of the ribs and terminating in a single cable thatextends into the carriage, and a, windlass within said carriage on whichthe cable is wound.

2. In a parachute, a centralrod, ribs pivoted at their upper ends tosaid rod, a runner mounted on the rod, stretchers extending between therunner and the ribs, a covering for the ribs, side arms. connected tothe lower end of the rod, a carriage carried by said side arms, ropesconnected to the free ends of the ribsand terminating in a single cableextending into the carriage,

, ing the cable.

In testimony whereof I an: my signature in presence of two witnesses.
